ABSTRACT:
A motor control apparatus for controlling a motor which selectively drives a first mechanism for moving a first object and a second mechanism for moving a second object. Both the first and second mechanisms having a backlash which occurs when the motor is reversed. The first mechanism moves the first object when the motor is rotated in a first direction and the second mechanism moves the second object when the motor is rotated in a second direction. The motor control apparatus includes a driving controller for rotating the motor at a predetermined angle in either the first direction or the second direction based on a predetermined instruction, a determining block for determining whether or not the motor is reversed, and a compensation block for compensating the angle at which the driving controller should rotate the motor so that an angle corresponding to the backlash is included in the angle at which the driving controller should rotate the motor.
